Famous quotes containing the word valleys:

    “But oh, not the hills of Habersham,
    And oh, not the valleys of Hall
    Avail: I am fain for to water the plain.
    Downward, the voices of Duty call—
    Downward, to toil and be mixed with the main,
    The dry fields burn, and the mills are to turn,
    And a myriad flowers mortally yearn,
    And the lordly main from beyond the plain
    Calls o’er the hills of Habersham,
    Calls through the valleys of Hall.”
    —Sidney Lanier (1842–1881)
